305-052-500-278

Edgeboard Connectors Overview

The EDAC Inc. 305-052-500-278 is a standard card edge connector from the 305 series, designed for dual-edge mating with a 52-position configuration. It features a 3.96 mm (0.156 inch) pitch and accepts PCBs with a thickness of 1.57 mm. The connector utilizes gold-plated copper alloy contacts to ensure reliable signal transmission and supports a continuous current rating of 5 A. It is constructed with a thermoplastic housing and employs wire hole termination for secure panel mounting. This component offers high insulation resistance and operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact termination style and housing color variations. Ensure that the ordering part number matches the required contact plating and current ratings for your application. Cross-reference the datasheet for dimensional tolerances to guarantee compatibility with your PCB design and panel cutouts before finalizing procurement.

Edgeboard Connectors Selection Notes

Select this connector when a dual-edge card interface with a 3.96 mm pitch is required. Consider the 5 A current rating and 1800 VACrms dielectric strength for electrical safety margins. Verify that the target PCB thickness aligns with the 1.57 mm specification. Evaluate the need for polarizing key compatibility if mechanical locking is necessary for the assembly.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series is characterized by its 0.156 inch pitch and versatile mounting options. Similar models in the series vary primarily by position count and termination type, offering a scalable solution for various interconnection needs within the same form factor and electrical specifications.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the EDAC 305 series include variants such as 305-052-500-568 or 305-052-500-268, depending on the required termination style and housing color. Verify that any replacement maintains the 52-position count and 3.96 mm pitch to ensure mechanical interchangeability.
